I have an attic roof to insulate, but i see little point in insulating the top sloping section. instead i will create a level false ceiling. The purlin which spans the room is perfect for building off. i then need to add a wall plate on the opposite wall.
Above the ceiling will be rock wool insulation and under it, 50mm kingspan and plasterboard.
the span is 1.5m.
1) What size timber do i use for the wall plate and can i use screw and plugs or do i need to go for rawl bolts?
2) What size timbers will i need ? Are 4x2 ok?
i also need some advise on the section section of the ceiling which is sloping and falls between 2 purlins. The span here is 2m and i want to again create a false ceiling, but this time go with the shape of the roof. What size timber do i use here?
i will sit the timbers on joist hangers and cut them to fit. Kingspan will be placed between and under them and then finished with plaster board.
if you are not sure on what i am trying to do i can explain more.
